Car was into the shop this week for the motor tick under the CPO warranty.
No questions asked they replaced the lifters and rockers based on my word alone. The repair document says:
Cause:
HVA
0058827
Correction:
Engine ticking at idle when cold.
Replaced lifters and rockers as per PUMA measure 25287832-10.
Relearned Valvetronic limit positions. Cleared Faults.

If anyone's curious or needs them, I can list the FP Numbers for all the parts too. I'm really glad I brought it in and got it looked at because they found an oil leak on a Camshaft sensor! Replaced an "Eccentric Shaft Sensor" under warranty yoo.

I don't know if it's a placebo effect, but the car seems to idle smoother a run better after having her top end cleaned up!
